It seems that iCloud and email servers are using Proofpoint for spam filtering.


We run a web hosting and email service company.  Proofpoint has blocked on of our IP addresses.  I have been trying for weeks to get a hold of someone at Proofpoint to get the IP delisted or to provide more information about the blacklist entry.  I'm not getting any responses.


If I were running the iCloud mail servers, I would strongly consider dropping Proofpoint as an email filtering system, since they seem to have fallen off the face of the earth.


The error message being returned by your server - ( - is:


550 5.7.0 Blocked - see


If someone with iCloud's server administration can provide me with a contact email address, I will send you the IP address that is being blocked.  If you can contact Proofpoint about this blacklisting it would be helpful.


I will also note that Proofpoint's lookup on our IP shows:


Most Recently Seen as Spam 03/01/2013 15:06:49 GMT


That was over 3 months ago.  Proofpoint is not maintaining their blacklist and is not providing a solid service.


We have filled out their form multiple times.  Two times:


05/30/13 - Request ID: 339705 - No Response

06/04/13 - Request ID: 340674 - No Response


If someone from iCloud wants to ask Proofpoint why they are not responding to the submissions on their form, there are two Request IDs.

    Same here. Submitted 2 false positive  forms to proofpoint to remove an IP address and nobody responded. 10 days later I'm still waiting.

    I'm also in the same boat. The record shows that my IP was blocked on 2011.


    I have sent dozen of requests, I have called them, talked to sales, threat them and nothing has worked. I even talked to Apple tech support and they start requesting none sense info from me.


    This is classic big company behavior: "Let's make money and screw everyone else!!!"


    They are too preocupied blocking everybody and have completely forgotten about updating records and helping the other end.


    Let's get together and fight these guys over the net. I'm willing to buy a the domain it is available. We have to some how get the attention of these guys.


    Any ideas???

    I'm guessing, due to the lack of any attention to this thread by iCloud support, that iCloud doesn't care a lick about this.


    Wrong. This is a user-to-user forum only. iCloud support are not here - that's why there's no response from them.


    If you want a response from iCloud Support, contact them directly. Don't post on a end user forum.

    Same boat here and with a brand new server and new IP.  Every large corp is going to try to force independant website owners into using their BS email so people can snoop.


    Horse Crap if you ask me.

    And same here.

    We got complaints from our customers about a week ago.

    Tried to get delisted for several times. No response.


    I found a lot of complaints on the web, even on proofpoint facebook page

    I have constructed an email for our complaining customers with all links about the lack of support.

    Maybe I can get someone to cancel their services with proofpoint

    We have the same problem. One of our servers has been blacklisted by Proofpoint, for reasons best known to themselves. It has never sent any bulk mail. It is not listed on any other blocklists. And requests to get it unlisted have been ignored, just like everybody else's.


    In some ways I'm not surprised, considering Proofpoint have bought SORBS (who were renowned for false positives and extreme intransigence and unhelpfulness).


    Like the previous poster I would suggest to Apple that they reconsider their use of Proofpoint spam filtering.

    Suggesting things to apple isn't done on this forum.  It's done here:

    I have the same exact situation as described by other's here. I manage a hosting company (with offices in Northern California, servers in Texas) but with one particular server which is indellibly blacklisted at ProofPoint with no rhyme or reason. I just got off the telephone with a very nice sounding man with sales at Proofpoint, he said he would escallate my de-listing request as urgent, but so far no response.


    This particular server IP is on NO other RBLs as indiciated with the MXToolbox blacklist check, and the reputation ranking is GOOD. Yet ProofPoint continues to block hundreds of email account users on this server from sending email to any address.


    Further, we have  extenisve, multi-layed security on this server with manifold protections applied to the email server specifically, and we have staff monitoring email transmission 24/7.


    We have repeatedly requested that ProofPoint at least supply us with a header or something similar which would give us an indication of why this server was blocked, and what we could possibly do about it. Met only with silence, I am starting to get the feeling that ProofPoint has gotten deep into the hardened cop syndrome that says "everyone is a crook".


    Apple Computers Inc. should know better, this is reflecting very bad on their company among hosting providers who may otherwise be strong advocates for their products. Speaking of which, purchased my first Mac in 1984 right after they went on sale, and we are very nearly an all Mac office here in the support department. However...

    Wrong?!  It says right at the top of the page: 

    Apple Support Communities > iCloud > > Discussions


    Pretty confusing, I would say, to be on the Apple Support page, but not connected to ANYONE at Apple.  What is the point of clicking on the "Support" link?

    No, it's pretty simple, not confusing.


    What do you expect a user to user forum for apple products to include in its name?  Microsoft?
